The Pivotal Function of SLC16A1 and SLC16A1-AS1 in Cancer Progress: Molecular Pathogenesis and Prognosis.

More than 300 membranes make up the SLC family of transporters, utilizing an ion gradient or electrochemical potential difference to move their substrates across biological membranes. The SLC16 gene family contains fourteen members. Proton-linked transportation of monocarboxylates can be promoted by the transporters MCT1, which the SLC16A1 gene family encodes. Glycolysis is constitutively up-regulated in cancer cells, and the amount of lactate produced as a result is correlated with prognosis. Further speaking, SLC16A1 plays an essential role in controlling the growth and spread of tumors, according to mounting evidence. Additionally, LncRNAs are the collective term for all genes that produce RNA transcripts longer than 200 nucleotides but do not convert into proteins. It has steadily developed into a hub for research, offering an innovative approach to tumor study as technology related to molecular biology advances. The growing study has uncovered SLC16A1-AS1, an RNA that acts as an antisense to SLC16A1, which is erroneously expressed in various types of cancers. Therefore, we compiled the most recent information on the physiological functions and underlying processes of SLC16A1 and the LncRNA SLC16A1-AS1 during tumor development to explore their impact on cancer treatment and prognosis. We compiled the most recent information on the physiological functions and underlying processes of SLC16A1 and the LncRNA SLC16A1-AS1 during tumor development to explore their impact on cancer treatment and prognosis. Relevant studies were retrieved and collected through the PubMed system. After determining SLC16A1 and SLC16A1-AS1 as the research object, we found a close relationship between SLC16A1 and tumorigenesis as well as the influencing factors through the analysis of the research articles. SLC16A1 regulates lactate chemotaxis while uncovering SLC16A1- AS1 as an antisense RNA acting through multiple pathways; they affect the metabolism of tumor cells and have an impact on the prognosis of patients with various cancers.

SEfficacy and safety of apatinib in the treatment of patients with platinum‑resistant ovarian cancer: A systematic review and network meta‑analysis.

At present, the optimal therapeutic approach for the treatment of platinum-resistant recurrent ovarian cancer remains to be fully elucidated. The present systematic review and network meta-analysis aimed to elucidate the relative efficacy and safety of apatinib, administered either as monotherapy or in conjunction with chemotherapy, compared with chemotherapy alone, for the treatment of platinum-resistant recurrent ovarian cancer. The PubMed, Embase and Wanfang Data electronic databases were searched, where the search spanned from the conception of the databases until April 2023. A quality evaluation was conducted and R software was used for network meta-analysis. Following inclusion and exclusion criteria screening, the present analysis included 17 clinical trials, combining data from 1,228 patients with platinum-resistant recurrent ovarian cancer categorized into the following three treatment cohorts: i) 555 patients who received apatinib plus chemotherapy; ii) 229 patients who received apatinib alone; and iii) 444 patients who underwent conventional chemotherapy. Results of the present study demonstrated that the co-administration of apatinib with either tegiol [odds ratio (OR), 2.54; 95% CI, 1.06-6.11] or etoposide (OR, 2.12; 95% CI, 1.20-3.74) significantly improved the objective response rate (ORR) compared with that following apatinib monotherapy. By contrast, gemcitabine monotherapy resulted in inferior ORR efficacy compared with that following apatinib (OR, 0.47; 95% CI, 0.23-0.95). In addition, combinations of apatinib with etoposide (OR, 1.32; 95% CI, 1.06-1.64) or paclitaxel (OR, 1.52; 95% CI, 1.04-2.23) demonstrated a significantly improved disease control rates (DCR) compared with those following apatinib alone. According to the area under the cumulative ranking analysis, apatinib and paclitaxel in combination was the most efficacious treatment modality in terms of DCR. In terms of safety, the incidence of adverse events, such as hand-foot syndrome [relative risk (RR), 4.23; 95% CI, 1.80-9.95] and hypertension (RR, 4.80; 95% CI, 1.53-15.05), was found to be significantly higher in patients treated with apatinib-containing therapies, compared with those treated with chemotherapy alone. Consequently, the present meta-analysis highlighted the potential of apatinib, particularly in combination with chemotherapy, as a therapeutic strategy for patients with platinum-resistant recurrent ovarian cancer.

To explore the mechanism of Maiwei Dihuang decoction in the treatment of non-small cell lung cancer (NSCLC) by using network pharmacology and LC-MS technology. The effective components in Maiwei Dihuang decoction were detected by liquid chromatography- mass spectrometry (LC-MS). Use the SuperPred database to collect the relevant targets of the active ingredients of Mai Wei Di Tang, and then collect the relevant targets of nonsmall cell lung cancer from GeneCards, DisgenNET and OMIM databases. On this basis, PPI network construction, GO enrichment analysis and KEGG pathway annotation analysis were carried out for target sites. Finally, AutoDock Vina is used for molecular docking. We further screened 16 effective Chinese herbal compounds through LC-MS combined with ADME level. On this basis, we obtained 77 core targets through protein interaction network analysis. Through GO, KEGG analysis and molecular docking results, we finally screened out the potential targets of Maiwei Dihuang Decoction for NSCLC: TP53, STAT3, MAPK3. Maiwei Dihuang decoction may play a role in the treatment of NSCLC by coregulating TP53/STAT3/MAPK3 signal pathway.

A Rationalized Approach to Design and Discover Novel Non-steroidal Derivatives through Computational Aid for the Treatment of Prostate Cancer.

Prostate cancer is one of the most prevalent cancers in men, leading to the second most common cause of death in men. Despite the availability of multiple treatments, the prevalence of prostate cancer remains high. Steroidal antagonists are associated with poor bioavailability and side effects, while non-steroidal antagonists show serious side effects, such as gynecomastia. Therefore, there is a need for a potential candidate for the treatment of prostate cancer with better bioavailability, good therapeutic effects, and minimal side effects. This current research work focused on identifying a novel non-steroidal androgen receptor antagonist through computational tools, such as docking and in silico ADMET analysis. Molecules were designed based on a literature survey, followed by molecular docking of all designed compounds and ADMET analysis of the hit compounds. A library of 600 non-steroidal derivatives (cis and trans) was designed, and molecular docking was performed in the active site of the androgen receptor (PDBID: 1Z95) using Auto- Dock Vina 1.5.6. Docking studies resulted in 15 potent hits, which were then subjected to ADME analysis using SwissADME. ADME analysis predicted three compounds (SK-79, SK-109, and SK-169) with the best ADME profile and better bioavailability. Toxicity studies using Protox-II were performed on the three best compounds (SK-79, SK-109, and SK-169), which predicted ideal toxicity for these lead compounds. This research work will provide ample opportunities to explore medicinal and computational research areas. It will facilitate the development of novel androgen receptor antagonists in future experimental studies.

Camptothecin and its Analogs: High-Yielding Ophiorrhiza Species from Sri Lanka for Sustainable Anticancer Compound Production

Introduction: Camptothecin (CPT) is pivotal in cancer treatment, derived from various CPT-producing plant species, and is a fundamental component in synthesizing valuable cancer drugs like Irnotican and Topotecan. Sourcing from nature poses conservation issues, fostering interest in the herbaceous Ophiorrhiza plant as a more sustainable alternative. Ophiorrhiza species in Sri Lanka lack comprehensive study, warranting exploration for echo-friendly anticancer compound production. Objectives: This study examines CPT and analog content in Ophiorrhiza mungos, O. pectinata, and O. rugosa across diverse Sri Lankan regions. Methods: The study employs Thin Layer Chromatography (TLC), High-Performance Liquid Chromatography-DAD (HPLC-DAD), and Liquid Chromatography-Mass Spectrometry (LC-MS) to quantify and confirm CPT and its analogs. Results: Significant variations in the content of CPT and its analogs were observed among plant parts and regions. O. mungos from Deraniyagala and Bibile regions notably exhibited elevated CPT levels in fruits and roots. O. rugosa var. Angustifolia and O. pectinata also exhibited a considerable content of CPT in their roots, though it was significantly lower (p < 0.005) than O. mungos. Conclusion: The study validates analytical methods for specificity, linearity, precision, accuracy, and sensitivity per ICH guidelines. The results indicate that Ophiorrhiza species, especially O. mungos and O. rugosa var. Angustifolia holds the potential to be a sustainable source of CPT. Optimizing cultivation practices offers an eco-friendly solution for anticancer compound production, alleviating species threats and conserving biodiversity.

Embedding Multimodal Rehabilitation Within Routine Cancer Care in Sheffield-The Active Together Service Evaluation Protocol.

Approximately 3 million people in the United Kingdom are currently living with or beyond cancer. People undergoing treatment for cancer are at risk of complications following treatment. Increasing evidence supports the role of rehabilitation (including prehabilitation) in enhancing psychological and physical well-being in patients with cancer and improving outcomes. Active Together is an evidence-based, multimodal rehabilitation service for patients with cancer, providing support to help patients prepare for and recover from treatment. This paper presents the evaluation protocol for the Active Together service, aiming to determine its impact on patient-reported outcomes and clinical endpoints, as well as understand processes and mechanisms that influence its delivery and outcomes. This evaluation comprises an outcome and process evaluation, with service implementation data integrated into the analysis of outcome measures. The outcome evaluation will assess changes in outcomes of patients that attend the serviceand compare health care resource use against historical data. The process evaluation will use performance indicators, semistructured interviews, and focus groups to explore mechanisms of action and contextual factors influencing delivery and outcomes. Integrating psychological change mechanisms with outcome data might help to clarify complex causal pathways within the service. Evidence to support the role of multimodal rehabilitation before, during, and after cancer treatment is increasing. The translation of that evidence into practice is less advanced. Findings from this evaluation will contribute to our understanding of the real-world impact of cancer rehabilitation and strengthen the case for widespread adoption of rehabilitation into routine care for people with cancer.

Steroid-refractory immune checkpoint inhibitor (ICI) hepatitis and ICI rechallenge: A systematic review and meta-analysis

Background: In recent years, the use of immune checkpoint inhibitors (ICIs) has become a cornerstone in cancer treatment. However, this has also resulted in the emergence of immune-related adverse events, notably ICI hepatitis, posing a significant clinical challenge. While steroids are the primary treatment, there are increasing cases of steroid-refractory ICI hepatitis. Our objective is to investigate the management of ICI hepatitis and its response to steroid treatment. Methods: PubMed/MEDLINE, EMBASE, and CENTRAL databases were searched in July 2023 based on keywords including ICIs (anti–Programmed cell death protein 1/Programmed Death-Ligand 1, anti–CTLA–4, and anti-LAG3) and hepatitis. Results: A total of 4358 studies were screened, and 44 studies were included in this systematic review. One thousand eight hundred fifty-six patients with ICI hepatitis were included (grade 1-2: 31.7%, grade 3-4: 56.0%, and unknown: 12.3%) with 1184 patients who received corticosteroid treatment. The duration of treatment and dosage varied considerably across the studies. Mycophenolate mofetil was the predominant agent used in 68 out of 82 cases (82.9%), followed by infliximab and azathioprine. A summary estimate of the proportion of steroid-refractory hepatitis in a random effects model was 16% (95% CI: 11%–23%). An estimated 40% (95% CI: 30%–51%) of patients of all patients with ICI hepatitis were rechallenged with an ICI, and of those rechallenged, there was an estimated 22% (95% CI: 15%–30%) recurrence. Conclusions: Corticosteroids are the primary treatment for ICI hepatitis, with mycophenolate mofetil used as a secondary option for steroids-refractory cases. Current practices mostly rely on expert consensus, highlighting the need for further research to validate and optimize these treatments, particularly for steroid-resistant cases.

The Tao of copper metabolism: from physiology to pathology.

As a transitional metal, copper plays a crucial role in maintaining the normal physiological activities of mammals. The intracellular copper concentration is meticulously regulated to maintain extremely low levels through homeostatic regulation. Excessive accumulation of free copper in cells can have deleterious effects, as observed in conditions such as Wilson's disease. Moreover, data accumulated over the past few decades have revealed a crucial role of copper imbalance in tumorigenesis, progression and metastasis. Recently, cuproptosis, also known as copper-induced cell death, has been proposed as a novel form of cell death. This discovery offers new prospects for treating copper-related diseases and provides a promising avenue for developing copper-responsive therapies, particularly in cancer treatment. We present a comprehensive overview of the Yin-Yang equilibrium in copper metabolism, particularly emphasising its pathophysiological alterations and their relevance to copper-related diseases and malignancies.

The Indispensable Roles of GMDS and GMDS-AS1 in the Advancement of Cancer: Fucosylation, Signal Pathway and Molecular Pathogenesis.

Fucosylation is facilitated by converting GDP-mannose to GDP-4-keto-6-deoxymannose, which GDP-mannose 4,6-dehydratase, a crucial enzyme in the route, carries out. One of the most prevalent glycosylation alterations linked to cancer has reportedly been identified as fucosylation. There is mounting evidence that GMDS is intimately linked to the onset and spread of cancer. Furthermore, the significance of long-chain non-coding RNAs in the development and metastasis of cancer is becoming more well-recognized, and the regulatory mechanism of lncRNAs has emerged as a prominent area of study in the biological sciences. GMDS-AS1, an antisense RNA of GMDS, was discovered to have the potential to be an oncogene. We have acquired and analyzed relevant data to understand better how GMDS-AS1 and its lncRNA work physiologically and in tumorigenesis and progression. Additionally, we have looked into the possible effects of these molecules on cancer treatment approaches and patient outcomes. The physiological roles and putative processes of GMDS and lncRNA GMDS-AS1 throughout the development and progression of tumors have been assembled and examined. We also examined how these chemicals might affect patient prognosis and cancer therapy approaches. GMDS and GMDS-AS1 were determined to be research subjects by searching and gathering pertinent studies using the PubMed system. The analysis of these research articles demonstrated the close relationship between GMDS and GMDS-AS1 and tumorigenesis and the factors that influence them. GMDS plays a vital role in regulating fucosylation. The related antisense gene GMDS-AS1 affects the biological behaviors of cancer cells through multiple pathways, including the key processes of proliferation, migration, invasion, and apoptosis, providing potential biomarkers and therapeutic targets for cancer treatment and prognosis assessment.

The therapeutic effects of mesenchymal stem cells and their secretome on oral squamous cell carcinoma.

Oral cancers are prevalent in the human population, particularly in unindustrialized countries. In 90 % of oral cancers, the tumors arise from squamous cells, which is called oral squamous cell carcinoma (OSCC). Despite new treatment strategies, the morbidity and mortality rates are still high. Current treatment options including surgery, chemotherapy, and radiotherapy are not effective in the treatment of the tumor. Cell therapy with mesenchymal stem cells (MSCs) is considered one of the leading strategies in cancer treatment. However, the field of MSC therapy in OSCC is immature and ongoing studies are being conducted in experimental and pre-clinical studies. Here, we reviewed these studies to figure out whether the use of MSCs could be worthwhile in OSCC therapy or not. Both native and engineered MSCs as well as their secretome have been used in the treatment of OSCC. It seems that genetically modified MSCs or their secretome could inhibit the tumorigenesis of OSCC. However, further pre-clinical studies are required to come to a conclusion.

Magnetosomes as Potential Nanocarriers for Cancer Treatment.

Magnetotactic bacteria (MTBs) and their organelles, magnetosomes, are intriguing options that might fulfill the criteria of using bacterial magnetosomes (BMs). The ferromagnetic crystals contained in BMs can condition the magnetotaxis of MTBs, which is common in water storage facilities. This review provides an overview of the feasibility of using MTBs and BMs as nanocarriers in cancer treatment. More evidence suggests that MTBs and BMs can be used as natural nanocarriers for conventional anticancer medicines, antibodies, vaccine DNA, and siRNA. In addition to improving the stability of chemotherapeutics, their usage as transporters opens the possibilities for the targeted delivery of single ligands or combinations of ligands to malignant tumors. Magnetosome magnetite crystals are different from chemically made magnetite nanoparticles (NPs) because they are strong single-magnetic domains that stay magnetized even at room temperature. They also have a narrow size range and a uniform crystal morphology. These chemical and physical properties are essential for their usage in biotechnology and nanomedicine. Bioremediation, cell separation, DNA or antigen regeneration, therapeutic agents, enzyme immobilization, magnetic hyperthermia, and contrast enhancement of magnetic resonance are just a few examples of the many uses for magnetite-producing MTB, magnetite magnetosomes, and magnetosome magnetite crystals. From 2004 to 2022, data mining of the Scopus and Web of Science databases showed that most research using magnetite from MTB was carried out for biological reasons, such as in magnetic hyperthermia and drug delivery.

Synergistic response of PEG coated manganese dioxide nanoparticles conjugated with doxorubicin for breast cancer treatment and MRI application

In this research work, we designed a smart biodegradable PEG-coated MnO2 nanoparticles conjugated with doxorubicin (PMnO2-Dox NPs) for dual chemo-photodynamic therapy and magnetic resonance imaging (MRI) application. This highly sensitive pH-responsive PMnO2-Dox NPs causes effective drug release under acidic pH environment. PMnO2-Dox NPs not only improves the efficacy of chemo-photodynamic therapy due to synergistic response as well as improved MRI imaging via boosting T1 MRI contrast. Manifold characterization techniques have been employed for materials investigation. Crystallography of PMnO2-Dox NPs were performed by using XRD analysis, which confirmed tetragonal crystal structure with an approximate crystallite size of 20–30 nm. Surface morphology was confirmed via SEM analysis, results indicated the spherical and asymmetric agglomerated nanocluster of PMnO2-Dox NPs. In in vitro bioassay, the anticancer activity of PMnO2-Dox NPs were tested against breast cancer (MCF-7) cell line using MTT test. Moreover, it can also inhibit the growth of primary and secondary cancers without light exposure. Results suggested that PMnO2-Dox NPs not only convenient for cancer treatment via combined chemo-photodynamic therapy but also address the way towards a comprehensive strategy for MRI application via bright contrast agent T1 after overcoming the problem of multidrug resistance (MDR) and synergistic response of therapeutic analysis.

Laparoscopic right gastroepiploic artery-sparing distal gastric tube resection with lymph node dissection for gastric tube cancer after esophagectomy: A novel surgical approach (with video).

Total resection of the gastric tube with lymphadenectomy for advanced gastric tube cancer is highly invasive and associated with severe complications. Other surgical option, partial gastrectomy or wedge resection, is insufficient if lymph node metastasis is suspected. Therefore, a technique balancing invasiveness and curability is required. First, we laparoscopically peeled off adhesions of the gastric tube, gastric mesentery (including the right gastroepiploic artery/vein), pericardial membrane, and aorta, up to the planned resection line. Subsequently, we cut the infrapyloric and right gastric arteries at their roots and dissected No. 5 and No. 6 lymph nodes. We taped and spared the right gastroepiploic artery and vein and dissected the tissues including No. 4d lymph nodes. Finally, the gastric tube was cut using a linear stapler, and the remaining gastric tube was anastomosed to the jejunum with a circular stapler. The mean operative time for the three cases treated using this intervention was 729 min. The patients were discharged on postoperative day 8 or 9 without any complications. They all remained alive and recurrence-free. This novel approach balances invasiveness and curability by leveraging the advantages of laparoscopy. The procedure was performed safely and reproducibly in three consecutive cases, providing another viable option for the treatment of gastric tube cancer.

Immune checkpoint inhibitors with or without radiotherapy in metastatic non‑small cell lung cancer: A meta‑analysis and literature review.

The combination of immune checkpoint inhibitors (ICIs) and radiotherapy has shown promise in the treatment of metastatic non-small cell lung cancer (NSCLC). The present meta-analysis aimed to determine the efficacy and safety of combining radiotherapy (RT) ICIs for the treatment of metastatic NSCLC. PubMed, Google Scholar, the Cochrane Library and Web of Science databases were searched for relevant articles up to February 1, 2023. Post-therapy outcomes such as progression-free survival (PFS), complete response, partial response (PR), progressive disease (PD), stable disease and adverse events (AEs) were analyzed. The meta-analysis was performed using RevMan 5.4 software. A total of seven studies involving 682 patients were included (384 patients who received ICI + RT vs. RT and 298 patients who received ICI + RT vs. ICI alone). No significant difference in PFS was demonstrated between the ICI + RT group and the RT group (heterogeneity: χ2=2.35; df=1; P=0.13; I2=57% and test for overall effect: Z=0.10; P=0.92). Conversely, patients in the ICI alone group had significantly decreased PR rates (heterogeneity: Τ2=0.00; χ2=2.13; df=3; P=0.54; I2=0% and test for overall effect: Z=2.57; P=0.01) compared with patients in the ICI + RT group. The ICI + RT group also had significantly lower rates of PD (heterogeneity: Τ2=0.00; χ2=0.91; df=3; P=0.82; I2=0% and test for overall effect: Z=2.52; P=0.01) compared with the ICI alone group. Safety analysis revealed no significant difference between patients who received ICI + RT and those who received RT in terms of grade 1 or 2 AEs. In conclusion, the combination of ICIs + RT demonstrates promising efficacy and safety for patients with metastatic NSCLC. However, clinical trials that have tested this combination are lacking, which emphasizes the need for further research.

Chemical Composition, In vitro and In silico Evaluation of Essential Oil from Ocimum tenuiflorum and Coriandrum sativum Linn for Lung Cancer.

Medicinal plants play an essential role in everyday life; plants highly contain therapeutic phytoconstituents commonly used to treat various diseases. This paper discusses the Chemical composition, In vitro antiproliferative activity and In silico study of essential oil extracted from Ocimum tenuiflorum (family Lamiaceae) and Coriandrum sativum (family Apiaceae). In present study GC-MS was used to identify the chemical constituents from O. tenuiflorum and C. sativum. In vitro antiproliferative activity was performed on A549 cancer cell lines. In silico study was performed by Schrodinger's maestro software to identify chemical constituents in both plants as potential EGFR inhibitors for the treatment of lung cancer. The essential oil was extracted by hydro distillation from aerial parts of O. tenuiflorum and C. sativum. The volatile oil sample was analyzed by (GC-MS) Gas Chromatography- Mass Spectrometry. Different chemical constituents were identified based on the retention index and compared with the NIST library. The oil samples from O. tenuiflorum and C. sativum was also evaluated for antiproliferative activity against human lung cancer A549 cell lines. In silico study was performed by Schrodinger maestro software against EGFR (PDB ID 5HG8). O. tenuiflorum essential oil contains Eugenol (42.90%), 2-β-Elemene (25.98%), β- Caryophyllene (19.12%) are the major constituents. On the other side, C. sativum contains nnonadecanol- 1 (16.37%), decanal (12.37%), dodecanal (12.27%), 2-Dodecanal (9.67%), Phytol (8.81%) as the major constituents. Both the oils have shown in vitro antiproliferative activity against human lung cancer cell lines A549 having IC50 values of 38.281 μg/ml (O. tenuiflorum) and 74.536 μg/ml (C. sativum). Molecular interactions of constituents hydro distilled from two oils was analysed by schrodinger maestro software against EGFR (PDB ID 5HG8). The oil sample extracted from O. tenuiflorum showed more antiproliferative activity than C. sativum. In silico study showed that two chemical constituents, namely di-isobutyl phthalate (-7.542 kcal/mol) and dibutyl phthalate (-7.181 kcal/mol) from O. tenuiflorum and one diethyl phthalate (-7.224 kcal/mol) from C. sativum having more docking score than standard Osimertinib which indicates the effectiveness of oils for lung cancer.
